The AI autonomously chose Three.js, generated textures via OpenAI's gpt-image-2, wrote Playwright tests to catch bugs, and committed iteratively to GitHub Pages for live previewing. The resulting game features 3D graphics, procedural audio, mobile touch controls, and escalating night-based difficulty with guards and a scent-tracking dog. While technically impressive as a one-shot output, the gameplay itself is shallow and easy — Willison notes that designing genuinely fun games remains a uniquely human skill that AI agents haven't cracked. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I preview a Claude Code for web session's progress in real time before it finishes? Create a GitHub repository, start a Claude Code for web session and have it commit an index.html quickly, then go to the repository's Settings > Pages, choose 'Deploy from a branch', select Claude's working branch, and save. Within about 30 seconds of each push, the latest content becomes visible at yourname.github.io/your-repo/, even for private repos, though anyone who guesses the repo name can view it. _Developers tracking new agent workflows like this can follow ongoing coding-agent tips on daily.dev._ ### Can Claude Code give an AI agent access to OpenAI's image generation API to create game textures? Yes, giving an agent like Claude Fable 5 an OpenAI API key and pointing it to the gpt-image-2 model documentation lets it write its own texture-generation scripts and produce assets such as ground textures and title-screen art. In one project it generated seven ground and wall textures plus title art, committing them as static assets so the deployed game needed no further API calls. _Anyone combining coding agents with image APIs can compare setups and results on daily.dev._ ### How good are AI-generated games built by autonomous coding agents like Claude Fable 5? They tend to be technically impressive but gameplay-wise mediocre. A raccoon-heist 3D browser game built by Claude Fable 5 from a single prompt included working mobile touch controls, procedural WebAudio music, generated textures, and a scent-tracking dog mechanic, but had no team mechanics, was very easy to beat, and became boring once all items were collected each night. _Developers weighing AI agents for game prototyping can compare experience reports like this on daily.dev._ ## Similar posts on daily.dev - [I let Claude Fable handle three beginner projects, and it one-shotted every single one](https://daily.dev/posts/i-let-claude-fable-handle-three-beginner-projects-and-it-one-shotted-every-single-one-o1yonnwvc) · XDA Developers · 2 upvotes · 0 comments --- Tags: [#game-development](https://daily.dev/tags/game-development), [#claude](https://daily.dev/tags/claude), [#vibe-coding](https://daily.dev/tags/vibe-coding), [#threejs](https://daily.dev/tags/threejs), [#github-pages](https://daily.dev/tags/github-pages) [View this post on daily.dev](https://daily.dev/posts/one-shotting-a-raccoon-heist-game-using-claude-fable-5-g4tsm2ybx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"One-shotting a Raccoon Heist game using Claude Fable 5","url":"https://daily.dev/posts/one-shotting-a-raccoon-heist-game-using-claude-fable-5-g4tsm2ybx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/one-shotting-a-raccoon-heist-game-using-claude-fable-5-g4tsm2ybx"},"datePublished":"2026-08-05T19:49:06.851Z","dateModified":"2026-09-14T09:00:31.275Z","description":"Simon Willison used Claude Fable 5 (via Claude Code for web) to build a fully playable 3D browser game called Raccoon Heist from a single prompt, inspired by a...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/5cdf32fe02cdec91648b53244a7ea9a9?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/5cdf32fe02cdec91648b53244a7ea9a9?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Simon Willison","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Simon Willison","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/cf12b897300740218b35f49a6309ec5b","url":"https://daily.dev/sources/simonwillison"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/one-shotting-a-raccoon-heist-game-using-claude-fable-5-g4tsm2ybx","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"game-development,claude,vibe-coding,threejs,github-pages","timeRequired":"PT12M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Simon Willison","item":"https://daily.dev/sources/simonwillison"},{"@type":"ListItem","position":3,"name":"One-shotting a Raccoon Heist game using Claude Fable 5"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/one-shotting-a-raccoon-heist-game-using-claude-fable-5-g4tsm2ybx#faq","mainEntity":[{"@type":"Question","name":"How can I preview a Claude Code for web session's progress in real time before it finishes?","acceptedAnswer":{"@type":"Answer","text":"Create a GitHub repository, start a Claude Code for web session and have it commit an index.html quickly, then go to the repository's Settings > Pages, choose 'Deploy from a branch', select Claude's working branch, and save.
